For those cases we need to adjust the mode a bit, but Jesse gmch pfit refactoring in commit 2dd24552cab40ea829ba3fda890eeafd2c4816d8 Author: Jesse Barnes Date: Thu Apr 25 12:55:01 2013 -0700 drm/i915: factor out GMCH panel fitting code and use for eDP v3 broke that by reordering the computation of the gmch pfit state with the block of code that prepared the adjusted mode for it and told the modeset core not to overwrite the adjusted mode with default settings. We might want to switch around the core code to just fill in defaults, but this code predates the pipe_config modeset rework. And in the old crtc helpers we did not have a suitable spot to do this.
